SystemDynamics: Systems Dynamics Library for Dymola/Modelica

Introduction

SystemDynamics is a graphical modeling methodology, designed in the realm of Dymola/Modelica families of modeling tools. SystemDynamics implements the approach to graphical modeling of ill-defined systems that had been conceptualized in the sixties by Jay Forrester at M.I.T.

The Systems Dynamics modeling methodology describes material flows through a physically motivated system. State equations are being obtained indirectly by the computation of material inflows and outflows. Tabular functions are being used to model imprecisely known and/or poorly understood phenomena.

The Systems Dynamics modeling methodology is particularly liked and used by biologists and economists, who find its easily understandable and mathematically non-challenging and non-threatening approach to describing poorly understood systems appealing.
